如何更改AlertDialog中的文本颜色?

<item name="android:textColor">@color/black_text</item> 

这只会改变标题颜色。

 ad = new AlertDialog.Builder((new ContextThemeWrapper(context, R.style.DialogTheme))); ad.setTitle(R.string.my_activ_remove_title_dialog); ad.setPositiveButton(R.string.my_activ_remove_dialog, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int arg1) { content.remove(position); notifyItemRemoved(position); notifyItemRangeChanged(position, content.size()); } }); ad.setNegativeButton(R.string.my_activ_cancel_remove_dialog, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int arg1) { } });

要仅更改字体颜色,请尝试以下操作:

  AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle(Html.fromHtml("<font color='#FF7F27'>This is a test</font>")); builder.setPositiveButton(Html.fromHtml("<font color='#FF7F27'>Yes</font>"), new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int arg1) { Log.e(LOG_TAG, "Yes"); } }); builder.setNegativeButton(Html.fromHtml("<font color='#FF7F27'>No</font>"), new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int arg1) { Log.e(LOG_TAG, "No"); } }); builder.create(); builder.show();

要更改字体颜色和button背景色,请尝试以下操作:

  AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(Html.fromHtml("<font color='#FF7F27'>This is a test</font>")); builder.setCancelable(false); builder.setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); AlertDialog alert = builder.create(); alert.show(); Button nbutton = alert.getButton(DialogInterface.BUTTON_NEGATIVE); //Set negative button background nbutton.setBackgroundColor(Color.MAGENTA); //Set negative button text color nbutton.setTextColor(Color.YELLOW); Button pbutton = alert.getButton(DialogInterface.BUTTON_POSITIVE); //Set positive button background pbutton.setBackgroundColor(Color.YELLOW); //Set positive button text color pbutton.setTextColor(Color.MAGENTA);

如果你想改变分隔线颜色,试试这个:

  AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("Test Title"); builder.setMessage(Html.fromHtml("<font color='#FF7F27'>This is a test</font>")); builder.setCancelable(false); builder.setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); AlertDialog dialog = builder.create(); dialog.show(); try { Resources resources = dialog.getContext().getResources(); int alertTitleId = resources.getIdentifier("alertTitle", "id", "android"); TextView alertTitle = (TextView) dialog.getWindow().getDecorView().findViewById(alertTitleId); alertTitle.setTextColor(Color.MAGENTA); // change title text color int titleDividerId = resources.getIdentifier("titleDivider", "id", "android"); View titleDivider = dialog.getWindow().getDecorView().findViewById(titleDividerId); titleDivider.setBackgroundColor(Color.YELLOW); // change divider color } catch (Exception ex) { ex.printStackTrace(); } Button nbutton = dialog.getButton(DialogInterface.BUTTON_NEGATIVE); //Set negative button background nbutton.setBackgroundColor(Color.MAGENTA); //Set negative button text color nbutton.setTextColor(Color.YELLOW); Button pbutton = dialog.getButton(DialogInterface.BUTTON_POSITIVE); //Set positive button background pbutton.setBackgroundColor(Color.YELLOW); //Set positive button text color pbutton.setTextColor(Color.MAGENTA); 

这是我的示例代码,但是如果您想要更改分隔线颜色,请考虑以“int titleDividerId”开始的部分代码。

如果你想定制AlertDialog很多。 例如,添加一些checkbox与自定义背景颜色,使用这种方法:

 AlertDialog.Builder alert = new AlertDialog.Builder(this); LinearLayout mainLayout = new LinearLayout(this); mainLayout.setOrientation(LinearLayout.VERTICAL); LinearLayout layout1 = new LinearLayout(this); layout1.setOrientation(LinearLayout.HORIZONTAL); CheckBox cb1 = new CheckBox(getApplicationContext()); cb1.setText("Easy"); layout1.addView(cb1); layout1.setBackgroundColor(Color.BLUE); layout1.setMinimumHeight(50); LinearLayout layout2 = new LinearLayout(this); layout2.setOrientation(LinearLayout.HORIZONTAL); layout2.addView(new TextView(this)); CheckBox cb2 = new CheckBox(getApplicationContext()); cb2.setText("Normal"); layout2.addView(cb2); layout2.setBackgroundColor(Color.CYAN); layout2.setMinimumHeight(50); LinearLayout layout3 = new LinearLayout(this); layout3.setOrientation(LinearLayout.HORIZONTAL); CheckBox cb3 = new CheckBox(getApplicationContext()); cb3.setText("Hard"); layout3.addView(cb3); layout3.setBackgroundColor(Color.GREEN); layout3.setMinimumHeight(50); mainLayout.addView(layout1); mainLayout.addView(layout2); mainLayout.addView(layout3); alert.setTitle("Custom alert demo"); alert.setView(mainLayout); alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); alert.setPositiveButton("Done", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(getBaseContext(), "done", Toast.LENGTH_SHORT).show(); } }); alert.show();

首先,我在代码中看到了一个主布局(垂直)。 然后,为每个checkbox创build一个水平布局。 在这种情况下,您可以使用元素的颜色和字体(checkbox,项目等)。 我希望它有帮助。

创build对话框之后:

 AlertDialog dialog = builder.create(); dialog.show(); Button buttonPositive = dialog.getButton(DialogInterface.BUTTON_POSITIVE); buttonPositive.setTextColor(ContextCompat.getColor(this, R.color.green)); Button buttonNegative = dialog.getButton(DialogInterface.BUTTON_NEGATIVE); buttonNegative.setTextColor(ContextCompat.getColor(this, R.color.red));
