XML配置文件中该标签有属性password="true"

这样只是变成圆点，不是星号

这个除非自定义控件吧，那样挺复杂的，好像没有其他简单的方法

[节操在此]

给你个方法

EditText t = new EditText(this);
		t.setTransformationMethod(new TransformationMethod() {
			
			@Override
			public void onFocusChanged(View view, CharSequence sourceText, boolean focused, int direction, Rect previouslyFocusedRect) {
				// TODO Auto-generated method stub
				
			}
			
			@Override
			public CharSequence getTransformation(CharSequence source, View view) {
				// TODO Auto-generated method stub
				return new SubCharSequence(source);
			}
		});

private class SubCharSequence implements CharSequence {
	    private CharSequence mSource;
	    public SubCharSequence(CharSequence source) {
	        mSource = source;
	    }
	    public char charAt(int index) {
	        return '*';
	    }
	    public int length() {
	        return mSource.length();
	    }
	    public CharSequence subSequence(int start, int end) {
	        return mSource.subSequence(start, end);
	    }
	}
